This post is from the Activity iPhone Duo SwiftUI Q&A.
For a guided SwiftUI flow with a blocking approval step, how would you recommend using the second display on iPhone Duo? For example, while the user waits for approval on one display, would showing the submitted information or other contextual content on the other display be an appropriate pattern?
As mentioned in the "Leverage multiple displays and scenes on iPhone Duo" talk, having scenes on both displays simultaneously is only supported for Camera apps:

Do do so with a camera app, you'd use the new CameraCaptureAccessory API.
